About me

Hi! I am Dr. Iriarte, and I'm an otolaryngologist, which is basically specializing in ears, nose, and throat. We see patients in our offices and also do surgery for these parts of the body.


My medical school training was done in the Midwest. I graduated from medical school at the University of Minnesota, and did my residency training in Wisconsin. Although the Midwest is beautiful, I was drawn back to California because my family lives here. Many people are surprised to find out that the harsh Midwest winters, although they can be long, was not what motivated me to return to my home state...I have lived here in California most of my life, and consider this to be my home. I enjoy the four seasons, and so I do look to the snow and the mountains in the winter time. During the summer, I enjoy the outdoors and I like traveling to far-away lands.

About my practice

During my encounters with my patients, I like to treat them as I would family, and many times my approach is straight forward. This is the way I believe I should be treated by my own doctor. I encourage you to ask questions and I take time to give explanations in simple terminology, so we are clear on what is being said. I'm a surgeon, but I also believe in trying other more conservative methods of treatment if so indicated. Our specialty is responsible for trying to keep the ears healthy by advising on what can cause hearing loss. We also care for nasal problems, such as a broken nose, that can affect your ability to breathe well. We also treat some allergies, etc. Along with taking care of your throat, we care for issues of the voice, swallowing, etc.

How I thrive

I believe in preventive medicine, and that everything in moderation is okay. Our mind is very important and we should try to have a positive outlook on life. I believe in looking at the glass half full rather than half empty. During my travels, I have learned to respect other cultures'' beliefs and rituals. My practice is to listen and understand what is causing so much concern to you. I try to be sensitive to the fact that there may be other ways of treating some ailments that may depart from our Western Medicine approach.
